<u>Answer:</u> The frequency of the radiation is 33.9 THz
<u>Explanation:</u>
We are given:
Wave number of the radiation,
Wave number is defined as the number of wavelengths per unit length.
Mathematically,
where,
= wave number =
= wavelength of the radiation = ?
Putting values in above equation, we get:
Converting this into meters, we use the conversion factor:
1 m = 100 cm
So,
- The relation between frequency and wavelength is given as:
where,
c = the speed of light =
= frequency of the radiation = ?
Putting values in above equation, we get:
Converting this into tera Hertz, we use the conversion factor:
So,
Hence, the frequency of the radiation is 33.9 THz
